DRAFT-EQUALIZER.

Application filed December 8,

To all whom it may concern:

Jossru W. Kai's, citizens of the United States, residing at .lfiugene,in the county of Lane and State of Oregon, have invented certain new anduseful improvements in .Draft-Equalizers, of which the lollow 'ing is aspecification.

This invention provides means for eqi'ializing the draft of three ormore horses when hitched to a machine or vehicle provided with a pole,or tongue, in such a manner as to admit of an unequal number of draftanimals being arranged upon opposite sides of the pole.

The invention consists of the novel features, details of eonstrtu-tionand combinatimis of parts which hereinal'ter will he more part ieularlyset .i'orth, illustrated and tin-ally embodied in the suhjoined claims.

In the drawings hereto attached and forming a part of thespeeilicatimrs: Figure l a top plan view of a l o dralt equalizershowing the three horses. Fig. .2

invention adapted for is a side view of the equalizer. Fig. .i is adetail persptaztive view showing more clearly the relative arrangement,of the different irons and connections.

hitched in the accustomed way.

The pole or tongue l, may be such as applied to any agriculturalmachine. or vehicle, designed to he propelled by having the draftanimals arranged upon opposite sides of the pole in unequal number. Thenumeral 2 indicates a lever i'nlcrumed at 3 so as to provide a short armand a long arm, the latter having a swinglelree at its outer end towhich an animal is A rod 4' connects the long arm oi the lev r 2 with acrank arm at one end of a shaft t5 which is journalcd to the pole, or

The lower iron '7 is provided with spaced wings 9 which embrace thepole. or tongue, and are bolted, or otherwise secured thereto. The rearportion of the iron 7 rests upon the pole, whereas the front portion and8 which are securml to in advance oi the wings 9 is spaced from the polea short distance so as to hold the lever 2 clear of the pole. The upperiron 8 rests upon the iron 7 and is secured thereto and to the pole. Thefront portion oi the iron 8 is off-set and spaced from the front portionof the iron '7 a distance to receive the lever 2 between them. Thefulcrum 5, consists of a bolt, or other lastening which connect-a thefront ends of the irons 7 and 8 and passes through the lever 2 to retainit in 1 place.

The lever 2 is arranged between the front Specification of LettersPatent.

' bent, so as to fit over the shaft 6 and form a keeper Be it known thatwe, \VILLIAM L. CHRYSLER and therefor.

The shaft 6 is provided at opposite ends with crank arms which arediametrically arranged, the arm 5 being pendent, whereas the crank arm10 at the opposite end of the shaft 6 extends upwardly and receives therear end ol a rod 11, or like connection, the front end of said rod11.]. being attached to a whilfletree 12 which is provided at its endswith swingletrees in the usual manner, to which horses are adapted to hehitched in, the well known way when the equalizer is in service.

A hell crank or link 13 connects the short arm of the lever 2 with thewhifiletree-TZ, one arm having a transverse arrangement, whereas theopposite arm is disposed longitudinally. The whil'llctree 12 projectsabout an equal distance upon. opposite sides of the pole, or tongue, andby reason of the connections of the shaft ti and lever 2, the draft isevenly distributed upon (apposite sides oi said pole.

The crank arms 5 and 10 are of unequal length, the latter being longerthan the former. It will be observed that the short arm of; the lever 2moves forward, the crank arm 10 correspondingly moves orward well as thehell crank 13, the latter in addition to its forward niovcn'ient,turning upon its pivotal connection with the short arm of the lever 2.It is noted that the single animal hitched to the long arm of the lever2 has the advantage of the increased leverage, hence is enabled to pulla proportionate amount; corresponding to the effective draft of each oithe animals hitched to the whi'illetreo.

Having thus described the invention, what is claimed as new is:

1. In a draft; equalizer, the combination of a tongue, a. leverfulcrumed upon the tongue to provide a. long; arm and a short arm, mean[or connecting a draft animal to the long; arm of the lever. a whillletree, a link loosely connecting the whillle tree to the short arm of thelover, a shaft jonrnaled upon the tongue transversely thereof andprovided ts opposite ends with oppositely disposed crankarlus, a rodconnecting one of the crank levers to the long arm of the lever, and asecond rod connectingthe opposite crank arm to the before mentionedwhillle tree.

2. In a dr equalizer, the combination of a tongue, :1 pair of plate.secured to the tongue, the forward ends of the plates being spaced fromeach other and from the tongue, a lever fulcrumed at an intermediatepoint between the spaced ends of the plates to provide a lone; arm and ashort arm, means for connecting; a draft animal to the lone; arm, awhitl'lc tree, a link loosely connecting the whillle tree to the shortarm, a shaft journaled between the before mentioned plates and providedat its opposite ends with crank arms, a rod connecting one ol? the crankarms to the long arm of the lever, and a second rod connecting theopposite crank arm to the before mentioned whillle tree.

3. 111 a draft equalizer, the combination of a pole, or

The rear portion of the iron 8 is grooved, or t tongue, an iron securedto said pole and having its front portion spaced therefrom, a secondiron placed upon the lower iron and secured thereto and to the pole, andhaving its front portion spaced from the front portion of the loweriron, a shaft journaled between the two irons and having oppositelydisposed crank arms of unequal length, a lever fulcrunied between thefront ends of said irons to provide arms of unequal length, a rodconnecting the long arm of the lever with the short crank arm of saidshaft, a whiifletree, a bell crank connecting; the whiflletree with theshort arm of said lever and a rod connecting the Whiifletree with thelong crank arm of the aforementioned shaft.

In testimony whereof we afiix our signatures in presence of twowitnesses.
